Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)

Detailed Description

After being informed about the investigation and the potential risks, all subjects giving written informed consent will undergo screening to determine eligibility for study entry. At week 0, subjects who meet the eligibility requirements will be randomised in open, intra-patient investigation, treated with BIOpH+ Psoriasis Medical Bath on one side, and comparative treatment on the other side for 8 weeks.

Interventions

  • Device: BIOpH+ Psoriasis Medical Bath
    • 20 min bath every day during 1 week and thereafter 20 min bath every second day for additional 7 weeks.
  • Device: Cetaphil Moisturizing Lotion
    • Cetaphil Moisturizing Lotion will be applied on the affected body area on the same days as the BIOpH+ Psoriasis Medical Bath is performed.

Arms, Groups and Cohorts

  • Experimental: BIOpH+ Psoriasis Medical Bath
    • BIOpH+ Psoriasis Medical Bath is bath. Each bath will take 20 minutes and number of bath during the entire study period is approximately 35 baths.
  • Active Comparator: Comparative device
    • Comparative device is Cetaphil Moisturizing Lotion. The lotion will be applied on the affected body area on the same days as the BIOpH+ Psoriasis Medical Bath is performed.

Clinical Trial Outcome Measures

Primary Measures

  • Change in Psoriasis Area and Severity Index (PASI) score from Baseline compared to week 8.
    • Time Frame: Baseline and week 8.
    • The PASI score is a validated, investigator instrument assessing the severity of psoriasis. The severity is combined with the percentage of affected area.

Secondary Measures

  • Dermatology Life Quality Index (DLQI)
    • Time Frame: Baseline and week 8.
    • A quality of life instrument and will evaluate how much the skin problems affects the study subject’s daily life. It is a 10-question questionnaire. Each question contains four response categories: 0=not at all, 1=a little, 2=a lot, and 3=very much. A higher score means worse outcome.
  • Psoriasis Area Severity Index (PASI)
    • Time Frame: Week 2 and week 4
    • It combines the severity (erythema, induration and desquamation) and percentage of affected area. A high score means worse outcome. The body is divided into 4 sections: Head, weight = 0.1 Arms, weight = 0.2 Trunk, weight = 0.3 Legs, weight = 0.4 For each section, the percent of area of skin involved is estimated and graded: 0. 0% of involved area <10% of involved area 10-29% of involved area 30-49% of involved area 50-69% of involved area 70-89% of involved area 90-100% of involved area Within each area, the severity is estimated for 3 clinical signs: erythema (redness), induration (thickness) and desquamation (scaling). Severity is measured on a scale from 0-4, from none to maximum. The sum of all 3 severity parameters is calculated for each body section, multiplied by the area score for that area, and multiplied for the weight of the body section, for a maximum score of 72.
  • Physician Global Assessment (PGA)
    • Time Frame: Baseline, week 2, 4, and 8
    • The Physician Global Assessment, is a 5-point scoring system that will be used to assess the overall disease severity. This treatment response on each visit will be scored: 0 =cleared, 1=almost clear, 2=mild 3=moderate, and 4=severe. A higher scores mean worse outcome.
  • Tolerability assessment
    • Time Frame: Week 2, 4 and week 8.
    • Tolerability assessment completed by the study subject about local tolerance regarding experience of pruritus and burning/stinging measured on a 5-point scale, or by questions to be answered with yes or no.
  • Usability /satisfaction assessments
    • Time Frame: Week 8
    • A questionnaire to be answered by study subject about investigational device usability and satisfaction measured on a 5-point scale, or by questions to be answered with yes or no.
